Hydrogenation processes for white-oil production from Ashal’cha heavy crude

It is shown that high-quality commercial-grade white oils can be obtained from heavy high-sulfur Ashal’cha field oil by hydrogenation processes using commercial aluminum-cobalt-molybdenum and aluminum-platinum catalysts. It is found that the 354-376 °C fraction of the oil contains organo-sulfuric co...

Description
Summary:It is shown that high-quality commercial-grade white oils can be obtained from heavy high-sulfur Ashal’cha field oil by hydrogenation processes using commercial aluminum-cobalt-molybdenum and aluminum-platinum catalysts. It is found that the 354-376 °C fraction of the oil contains organo-sulfuric compounds that are most resistant to hydrogenolysis, which must be taken into account in producing the white oils. It is established that in terms of a number of characteristics, concentrates of paraffinic-naphthenic hydrocarbons correspond to white oils suitable for perfumery and the pharmaceutical industry.
